In-line Check Valve

In-line check valves are referred to check valves which are similar to the lift check valves. While, this valve generally has a spring that will 'lift' when there is stress on the upstream side of it. The stress needed on the upstream side of the valve to conquer the spring tension is regarded as the 'cracking pressure'. When the stress going through the valve goes below the cracking stress, the spring will shut down the valve to avoid backflow in the process.

In-line check valves apply to various industries such as building maintenance food, beverage & pharmaceutical, chemical processing, gas transmission and etc. Furthermore, application of the products includes compressor discharge, cryogenics, hydraulic lines, refrigeration, vacuum breaker and etc. Please contact us for further information.
